How to Install Windows XP and Remove Windows Vista

How to Install Windows XP and Remove Windows Vista
Windows Vista is not yet perfected and chances are you will reach the point where you want to revert to Windows XP. But the task is easier said than done especially if you want a clean copy of Windows XP on your PC. With that in mind, what can you do to uninstall Windows Vista and install Windows XP on your computer? Well, I had that problem last week and much as I looked for solutions on the web, I discovered a different way to remove Windows Vista and install a fresh Windows XP operating system.

How? Follow these steps.

1. Grab a hold of the usual bootable DOS disk. Some peripherals (particularly laptops) no longer come with the traditional floppy drives but not to worry. You can still download the DOS system from sites and burn them on a CD which you can use to boot.

2. Boot up your PC using the CD ROM as your first boot device. Allow it to load and then run the handy FDISK like before.

3. View the partitions on your hard drive and delete them one by one. Make sure you don’t leave any drive intact to make sure you get a RAW drive ready for formatting.

NOTE: As far as backups are concerned, this guide assumes that they have been already backed up or that the user wants to completely erase the Windows Vista OS.

4. After all partitions have been deleted or removed, place your Windows XP setup disk and restart the computer. Now you can install the Windows XP OS as you would in any first time setup. Some people have tried to use the dual boot which is really ridiculous.

For one, it eats up space and second why would you leave an operating system when you have no plans of using it. Some have even said that it causes problems so why leave it there in the first place?

Also, if at times you are attempting to overwrite Windows Vista, chances are your Windows XP setup will not even reach the first screen setup (blue screen). Such is the problem I had experienced that led me to find an alternative to which is itemized above.

These steps are guaranteed. Don’t let Windows Vista be a pain. You can outthink Windows Vista using the traditional way of formatting a computer, similar to the first time you install Windows XP.

Lessons from getting hit by a computer virus

For the 10th time, I got hit by a computer virus. This time, though, it was a nasty hit. I was happily surfing the Internet last weekend when my antivirus software started detecting it. I am not yet sure if it is a Trojan (a malicious program that leaves a backdoor open in your system for hackers to take control), or a computer worm (self-replicating malware). But it was clear. It was annoying and it took control of my laptop. As one saying goes, there are many ways to skin a cat. The most effective and y et desperate way to get rid of a computer virus is to format the computer. Wipe the hard drive clean, and start afresh. But that would mean losing all your important files, data, and programs -- not to mention wasted man hours in reinsta lling the operating system, drivers, etc. So that wasn't an option. I had to fi nd a way to take out the computer virus with surgical precision. A friend who is computer virus expert told me that getting rid of a computer virus is like peeling an onion. No, it does not make you cry. You have to pass th rough several layers to get to the juicy part.

It took me to kill da bastard . We ran full scans, using both my existing antivirus software and an online free service from Trend Micro. The software was able to detect it. It was called CRYP_NSANTI. It was a Trojan. But when we chec ked for a solution, there was none at this time. I Googled it and found that ot hers have recently been hit, and were asking how to get rid of it. He used a free trial antivirus software version from Avira and launched a Filipino-made solution called Noob Killer, which fixed Windows registries in my system. You c an Google both and find a way to download the software. Noob is apparently a solution developed by Pinoy techies. The free antivirus detected 30 more infected files.

They were all quarantined. The Noob Killer was then launched, correcting registries affected by th e computer virus. I asked what Noob Killer did to the nasty computer malware, a nd our in-house techie said that it "patched" the damaged "autorun" configurati on of my system, and sought other computer viruses/worms that are spreading through removable medias. Lessons: if you're patient enough, there are free and effective fixes online. But you have to have an expert with you when using such software. Also, numerous free trial versions of antivirus software are on the Internet. You can download them and use them to scan and quarantine computer viruses. Finally, it is bes t to update your antivirus software.

If it's a corporate account, then ask your network administrator if it comes with the latest fixes. More lessons: be careful in deleting files during computer virus scans. It is b est to quarantine them first. Also always make sure that you scan removable med ia you plug in to your computer. That means USB thumb drives, external hard dis k drives, and other media. Computer worms are now spreading through removable media, and it can be a nasty problem. Finally, I learned that today's computer viruses will not necessarily render your system useless. But when not dealt with quickly, it would. In past discussions with computer virus experts, computer malwares are increasingly being launch ed to steal passwords, usernames, and other personal information on an infected system. So when you're infected, it is best to seek the help of an expert. You would never know that they are just sitting in a little corner in your office.

Common Problems in PC crashes

Common Problems in PC crashesHere are some Common Problems in PC crashes. Your computer slows down, and part of the screen goes either black or white. This usually means that you’re using too many applications or programs all at once, and your computer can’t handle it. Try pressing ctrl+alt+delete, and look for the program that giving you trouble (usually labeled “not responding”), then try closing the said application by clicking end task. And if your computer is still in the line age of the dinosaur, try not to do all things at once. You might end up with less than you want to gain. Also, this may mean that your 20 years old version computer needs some upgrading like increase of RAM, or better yet, a new computer.

You removed some files or programs from your PC, and the next time you boot up, it won’t.
All computer operating systems (OS) have their own standard files and applications that will render the computer inoperable if you remove them. It safe to say that in windows, whatever was installed in your PC should not be removed, because windows will look for it when you boot up again. Also don’t simply delete programs that look unnecessary or uninstall them. When you boot up, windows system files look for programs that have been installed, so whether you remove the program manually or accidentally, you’re bound to get in trouble.

You installed a new hardware and software, and get a fatal exception error (or something like that). That’s what you called “Blue Screen of Death”. You might have installed something that is incompatible with your OS, it might be a new sound card, RAM, device driver, software. Try to remove that hardware that you installed or download the latest software updates for that particular hardware. Also pieces of advice, if you are unsure about installing something, try to find someone who knows better.

Why doesn’t my PC shut down, why is it so slow? When about to shut down your PC, allow a few minutes for some rest time. Illegal shutdowns can result in more permanent damage to your files or worst to your PC as well. The system might still be resolving something, maybe like cleaning up temporary files or folders, reallocating memory. This will help prevent from crashes. Try to backup your files on another media, like CD, DVD, or another hard disk. When your system fails, you can still restore your files. Screensavers and desktop themes along with a huge desktop picture of you and your boyfriend/girlfriend can also eat up resources, so try to disable those, or get one that’s not too heavy. Regular system maintenance can prevent slowing down or crashes of your PC. Try to run disk defragmenting and scan disk sessions, virus scanning, dust cleaning, and cleaning up unwanted files. That’s all folks thanks for reading.

PC Operation NC-II by TESDA

National Certification (NC) is a TESDA (Technical Education and Skills Development Authority) program for middle level skills development. National Certification Level assessment is a process of determining the qualification and certification level of a person based on competency assessment. It measures the person’s possession and application of knowledge, skills and attitudes to perform work activities to the standard expected in the workplace. Competencies within a specific level of qualification are small units of work that can merit a person/worker a job after completion. Therefore, completion of a certain competency would assure the industry that a person can perform a specific task/work.
